There are two types of fees: Trade fee and Overnight financing.
Trade fee is incurred each time you buy or sell assets on the market (i.e. each time you open and close a position).
Current trade fees on margin Trading accounts are:
0.05% for Cryptocurrencies
0.001% for Forex
0.01% for Indices and Commodities
Trade fees on Covesting Strategy accounts depend on current Followers' Equity of a Strategy, as explained here.
Overnight financing is due for any position that is carried into a new trading day (past 00:00 UTC) and is withheld from Trading account balance. A trading day lasts from 00:00 UTC to 23:59 UTC. Any position closed before 00:00 UTC will not be charged at all.
